Code, Safety, and Compliance

Your exhaust system must do more than spin—it must meet code and protect occupants. We design and service to NFPA 96 (kitchen), IMC/CMC, California Title 24, and local Long Beach permitting requirements. We also consider South Coast AQMD guidance and best practices for noise and energy. Our documentation and commissioning streamline approvals and inspections.

Energy Efficiency and Controls

We help lower operating costs with right‑sized fans, high‑efficiency EC motors, variable frequency drives (VFDs), demand‑controlled ventilation, premium belts and pulleys, and smart scheduling. Balanced make‑up air reduces drafts, improves kitchen comfort, and protects HVAC performance—supporting healthier indoor air quality and our core mission: healthy air for a healthy life.
